Kendrick FireFly Telrad Heater - 2003-FFR


Firefly Heaters

Kendrick's new FireFly heaters are designed for the astronomer who requires a dew prevention system that is both economical in price and power. Although unable to perform up to the high standards of Kendrick's original Premier brand of heaters, astronomers and anyone else requiring heated optics for dew prevention can depend on our FireFly heaters to perform under all but the most demanding observing conditions. Note that if your observing site gets temperatures that approach freezing on the nights you like to observe, you should consider the Premier line of heaters.

Having lower power requirements than Kendrick's Premier heater line, these heaters will extend the life of your battery between charges. Using a different heater technology but operating under the same principle as Kendrick's Premier line of heaters, these heaters will mildly disperse heat into your optics without compromising the figure of your telescope or camera optics.

As well, because of Kendrick's unique manufacturing process, the FireFly heaters will direct their heat into your optics instead of losing it into the atmosphere. Kendrick has had these heaters independently tested for heat transmission. These heaters are very effective in directing most of the heat into the optics which is important if dew is to be prevented. Kendrick uses high quality Velcro, elastic and connectors with these heaters. All the FireFly heaters come branded with their permanent, white identification label for easy identification in the field.
